[0002] The centrifugal pellet dryer, also known as the pellet centrifugal dryer, is an important part of the underwater pelletizing equipment. Its function is to dehydrate and dry the polymer compound pellets (for example, thermoplastic polyurethane, polyethylene, polypropylene, polyester and rubber pellets, etc.)-water mixture formed after underwater extrusion pelletizing. In the prior art, the centrifugal pellet dryer may overflow in some cases, such as when the pelletized pellets are too large, which affects the operating efficiency.

[0003] Since the centrifugal pellet dryer is the main post-processing equipment for underwater pelletizing production, the operating efficiency of the centrifugal pellet dryer will significantly affect the operation of the entire underwater pelletizing equipment. Therefore, those skilled in the art always hope to continuously improve the operation of the centrifugal pellet dryer to optimize the underwater pelletizing production. Utility Model Content

[0004] During the research and development process, the inventors realized that the centrifugal particle dryer may overflow in some cases. For example, during operation, a solid-liquid mixture containing particles and water enters the centrifugal particle dryer, and large particles with larger sizes are first filtered out at the large particle filter unit. However, in some cases, the proportion of large particles is high, and the large particle filter unit cannot discharge the large particles in time, so that the solid-liquid mixture cannot smoothly pass through the large particle filter unit, resulting in overflow.

[0005] This overflow phenomenon will bring safety hazards and pollution. If the overflow is directly collected by a drainage trough, the particles carried by the overflow will have the risk of clogging the drainage trough. In addition, due to the uncertainty of the overflow flow, when the overflow flow is greater than the discharge flow of the drainage trough, the overflow will be retained, affecting production.

[0006] In order to solve the overflow problem of centrifugal granule dryer in the prior art, the purpose of the utility model is to provide a solid-liquid mixture processing device for processing overflow of centrifugal granule dryer and a centrifugal granule dryer component that can solve the above problem.

[0008] In addition, the utility model also provides a centrifugal particle dryer assembly, comprising: a centrifugal particle dryer, a drainage trough, and a solid-liquid mixture processing device for processing overflow of the centrifugal particle dryer as described above;

[0009] Wherein, the solid-liquid mixture processing device for processing the overflow of the centrifugal granule dryer is arranged between the centrifugal granule dryer and the drainage ditch, the overflow port of the centrifugal granule dryer faces the water inlet of the solid-liquid mixture processing device for processing the overflow of the centrifugal granule dryer, and the drainage port of the solid-liquid mixture processing device for processing the overflow of the centrifugal granule dryer faces the drainage ditch.

[0017] Figure 6 The three-dimensional diagram schematically shows another embodiment of the solid-liquid mixture processing device for processing overflow of a centrifugal particle dryer according to the present invention. DETAILED DESCRIPTION

[0018] In this specification, the terms "top, bottom, side, horizontal direction, vertical direction" are used in conjunction with Figure 1 The orientation shown is divided as a reference.

[0019] In this specification, the "lowest edge of the drain outlet" refers to the lowest position of the drain outlet in the vertical direction. The "collection basket is inclined" means that the collection basket is at an angle to the horizontal direction.

[0020] In the present invention, although "water" may be used as "liquid" when describing a specific embodiment, it should be understood that in the present invention, both "liquid" and "water" are applicable.

[0021] In one aspect, the utility model provides a solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer, the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer is in a hollow form, including: a water inlet arranged at the top and a drain arranged at the side; the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer also includes a particle collector, the particle collector includes: a collection basket, a hanging arm and a hanging ear; wherein the collection basket is provided with a plurality of holes or is in a mesh shape, and the size of the collection basket corresponds to the inner diameter of the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer; the hanging arm extends upward from the edge of the collection basket, the hanging ear is arranged at the far end of the hanging arm, and the hanging ear is detachably engaged with the edge of the water inlet (for example, hook engagement or latch engagement), so that the particle collector is suspended inside the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer. In use, the overflow from the centrifugal particle dryer first enters the interior of the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer through the water inlet. In this interior, the particles in the overflow are settled in the particle collector, and the remaining water is discharged through the drain. In addition, when the particles collected by the particle collector reach a certain amount, the particle collector can be taken out to clean the particles.

[0022] Preferably, the distance between the lowest edge of the drain port and the bottom of the solid-liquid mixture processing device for processing the overflow of the centrifugal granulator dryer is not less than 8 cm. In this way, the overflow entering the solid-liquid mixture processing device for processing the overflow of the centrifugal granulator dryer can be ensured to stay for a sufficient time, thereby achieving sufficient sedimentation of the particles.

[0023] In a preferred embodiment of the solid-liquid mixture processing device for processing overflow of a centrifugal particle dryer of the utility model, the drain port is further provided with a filter screen, which prevents the particles from being discharged from the drain port when the particles are not sufficiently settled.

[0024] In a preferred embodiment of the solid-liquid mixture processing device for processing overflow of a centrifugal granulator dryer of the utility model, the drain port is further provided with an opening and closing mechanism capable of selectively opening and closing the drain port. The opening and closing mechanism enables the drain port to be closed in certain circumstances (e.g., when the overflow flow is too large) to prevent the overflow from impacting the drain tank.

[0025] In a preferred embodiment of the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer of the utility model, the drain port can adjust the position in the vertical direction. It should be understood that in the process of long-term use, if the amount of sedimented particles is too much, the internal space for achieving sedimentation will decrease, affecting the sedimentation effect. In extreme cases, the height of the sedimented particles can even reach the drain port, so that the entire solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer completely loses its function. Therefore, the configuration of the drain port described above that can adjust the position in the vertical direction makes it possible to extend the use time of the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer by adjusting the position of the drain port upward when the amount of sedimented particles is too much. More preferably, the drain port includes: a long hole arranged on the side of the solid-liquid mixture processing device for processing the overflow of a centrifugal particle dryer, and a drain plate; the drain plate is provided with a boss, and the boss is provided with a through hole for drainage; wherein the boss is arranged in the long hole, and the boss can adjust the position in the vertical direction relative to the long hole. In this way, the position adjustment of the drain port in the vertical direction can be achieved. The arrangement of the long hole and the drain plate described above enables the position of the drain port to be adjusted while maintaining liquid sealing, and has the advantages of simple structure and large adjustable range.

[0026] In a preferred embodiment of the solid-liquid mixture processing device for processing overflow of a centrifugal particle dryer of the utility model, the drain outlet is a plurality of drain outlets arranged in a vertical direction, wherein each drain outlet is provided with an opening and closing mechanism capable of selectively opening and closing the drain outlet. More preferably, the plurality of drain outlets are arranged at equal intervals. The multi-drain outlet structure described above enables one of the drain outlets to be selectively opened according to the sedimentation of the particles. Specifically, when the amount of particle sedimentation is too much, the current drain outlet can be closed and the upper drain outlet can be opened. In this way, a technical effect similar to that of adjusting the position of the drain outlet is achieved, with the advantage of easy operation.

[0027] In a preferred embodiment of the solid-liquid mixture processing device for processing overflow of a centrifugal particle dryer of the utility model, the collecting basket includes: a high side with a higher height in the vertical direction, and a low side with a lower height in the vertical direction, so that the collecting basket is inclined. It should be understood that when the collecting basket of the particle collector is arranged horizontally, when the particle collector is taken out, most or even all of the holes or meshes of the collecting basket may be blocked by particles, and the water above the particles cannot smoothly pass through the particle collector, so that there is a risk of water overflow. Alternatively, when the collecting basket is arranged in an inclined state, the settled particles tend to move toward the low side of the collecting basket, so that at least the holes or meshes on the high side will not be blocked by the particles, thereby avoiding water overflow.

[0028] In a preferred embodiment of the solid-liquid mixture processing device for processing overflow of a centrifugal granulator of the present invention, the solid-liquid mixture processing device for processing overflow of a centrifugal granulator further comprises a drain valve, which is used to empty the interior of the solid-liquid mixture processing device for processing overflow of a centrifugal granulator.

[0029] In a preferred embodiment of the solid-liquid mixture processing device for processing overflow of a centrifugal granulator dryer of the utility model, the solid-liquid mixture processing device for processing overflow of a centrifugal granulator dryer further comprises a liquid level gauge and / or an observation window. The liquid level gauge is used to observe the liquid level inside the solid-liquid mixture processing device for processing overflow of a centrifugal granulator dryer, and the observation window is used to observe the liquid level and particle sedimentation condition inside the solid-liquid mixture processing device for processing overflow of a centrifugal granulator dryer.

[0030] In another aspect, the utility model provides a centrifugal particle dryer assembly, comprising: a centrifugal particle dryer, a drainage tank, and a solid-liquid mixture processing device as described above for processing overflow of the centrifugal particle dryer;

[0031] Wherein, the solid-liquid mixture processing device for processing the overflow of the centrifugal granule dryer is arranged between the centrifugal granule dryer and the drainage ditch, the overflow port of the centrifugal granule dryer faces the water inlet of the solid-liquid mixture processing device for processing the overflow of the centrifugal granule dryer, and the drainage port of the solid-liquid mixture processing device for processing the overflow of the centrifugal granule dryer faces the drainage ditch.

[0032] In a preferred embodiment of the centrifugal granulator assembly of the utility model, the overflow port of the centrifugal granulator and / or the water inlet of the solid-liquid mixture processing device for processing the overflow of the centrifugal granulator are also provided with a guide plate, and the guide plate is used to guide the overflow from the overflow port, so that the overflow flows along the inner wall of the solid-liquid mixture processing device for processing the overflow of the centrifugal granulator and / or enters the solid-liquid mixture processing device for processing the overflow of the centrifugal granulator along the tangent of the inner wall of the solid-liquid mixture processing device for processing the overflow of the centrifugal granulator. This prolongs the sedimentation time, reduces the disturbance of the overflow to the settled particles, and thus improves the sedimentation effect.

[0033] The various components of the solid-liquid mixture processing device for processing overflow of a centrifugal granulator dryer of the utility model can be made of materials such as plastic or metal, and prepared by common processing and forming methods. Alternatively, the various components directly use commercially available products, and after assembly, they become an integral device that meets the requirements of the utility model. If plastic materials are used, the commonly used processing and forming methods are injection molding, molding, extrusion molding and other methods. If metal materials are used, the commonly used processing and forming methods are machining, casting, stamping, bending and other methods.

In use, the solid-liquid mixture processing device for processing the overflow of a centrifugal granulator of the present invention is arranged between the centrifugal granulator and the drain, and is used to process the overflow of the centrifugal granulator. The particles in the overflow can settle inside the solid-liquid mixture processing device for processing the overflow of the centrifugal granulator, and at the same time, the impact of the overflow flow change of the centrifugal granulator on the drain is alleviated. In addition, the present invention also provides the following preferred embodiments.
